Answer:

1433 m^2

Step-by-step explanation:

Area of the triangle

16 x 16 x 1/2 = 128

Area of the hexagon

A = \frac{3\sqrt{3} }{2} *a^2

a is a side of the hexagon

A =  \frac{3\sqrt{3} }{2} * 16^{2} = 665.1075101...

There are 6 triangles so...

128 x 6 = 768

Therefore the surface area is

665.1075101... + 768 = 1433.10751 m^2

There are 140 people in a singing competition. The graph shows the results for the first five rounds
SOVA2 [1]

a) The expression is y = 140 - 15 x

b ) There are 5 participants in the 9th round

Step-by-step explanation:

Step 1 :

From the graph we can see that,

Number of people in the singing competition = 140

Number of people in the first round = 125

Number of people in the second round = 110

Number of people in the third round = 95

Number of people in the fourth round = 80

Number of people in the fifth round = 65

Step 2 :

From the given data, We can get that the difference between the number of people participating in each round is 15 less than the previous round .

The first round has 15 people less than the total number 140

Let x represent the number of the round and y represent the number of people participating in each round .

Then the expression to represent this would be

y = 140 - 15 x

Step 3 :

To find the number of participants in the 9th round given the same pattern continues.

For the 9th round x = 9, as x represents the number of the round

Substituting this in the equation obtained in step 2, we get

y = 140 -15 (9) = 140 - 135 = 5

There are 5 participants in the 9th round

Step 4 :

Answer :

a) The expression is y = 140 - 15 x

b ) There are 5 participants in the 9th round

PLEASE HELP!!
Nesterboy [21]
First, we need to find the volume of the pan.  We do this by multiplying the length, width, and height together.  This is:

volume=10*12 \frac{1}{2} *2=250 in^{3}

Next, we find the volume of the pieces of bread.  We do this the same way.

volume=2*2 \frac{1}{2}*2=10in^{3}

Finally, we figure out how many times 10 can go into 250.  We do this by dividing 250 by 10.

250/10=25, so Arla can cut 25 pieces of bread.

23 × 32 is the prime factorization for which one of these choices?
forsale [732]

Hello.

Here's our explanation: First, you had to multiply line them up. 2*3=6, then 3*3=9. Bring down the zero, then multiply 2*2=4. And 3*2=6, which gives us equal to 640. Finally, add it up, 96+640=736. 736 is the final answer.

Hope this helps!

Thanks!

Have a great day!
